Thanks wolfden, it appears to be a problem with the version of xulrunner. The latest version of firefox in portage is 3.5.1-r10. When i try to install that version it automatically emerge the version 1.9.1-r11 of xulrunner and doesn't work. So, i install the versions 4.8 of nspr, 1.9.1-r1 of xulrunner and 3.5.1 of firefox, and it works fine.For anyone who has this problem:
